Which is a chemical property of magnesium?flammability
density
melting point
magnetism
Answers
Answer:
flammability
Explanation:
As we know that chemical property of an element will show it's chemical reactivity and its chemical nature on exposing to a reaction.
While physical properties are those which can be measured by some experimental means.
So here we know that all the measurable quantities are
1). Density
2). Melting Point
Here one of the given option is phenomenon in which all the domains of magnet align itself in direction of external magnetic field it is known as Magnetism.
So here correct chemical property is
Flammability.
Final answer:
The flammability of magnesium is the chemical property among those listed. It depicts how it changes to magnesium oxide when heated in an oxygen environment.
Explanation:
The property listed that is a chemical property of magnesium is its flammability. Chemical properties describe how a substance interacts with other substances or changes from one substance to another. Flammability, meaning the ability to burn in the presence of oxygen, is a chemical property because it describes how magnesium will change to magnesium oxide when heated in air.
On the other hand, properties such as density, melting point, and magnetism are physical properties because they describe the physical state of the magnesium and not how it interacts with other chemicals.

What is problem solving?
Problemsolving, which is a common part of most activities, is the process of achieving a goal by overcoming obstacles.
Problems that require resolution range from simple personal tasks to complex issues in business and technology.
7 Steps can be followed to allow the problem solving success
- Step 1: Identifying the Problem.
- Step2: Establishing Objectives.
- Step three is brainstorming.
- Step 4: Evaluate Alternatives
- Step 5: Selecting a Solution
- Step 6: Active Implementation of the Selected Solution
- Step 7 is an evaluation.
Fearless problem solvers share five key characteristics: they are unafraid, optimistic, driven, smart, and empathetic.
Thus, the correct option is c, i.e., identifying the problem.

Hello!
The potential energy of a 25 kg bicycle resting at the top of a 3 m high hill is _______ J
If: 1 Joule = 1 kg.m²/s²
We have the following data:
GPE (Gravitational Potential Energy) = ? (in J)
m (mass) = 25 kg
g (gravity) ≈ 9.81 m/s²
h (height) = 3 m
We apply the data to the formula of the gravitational potential energy, we have:

- Increases levels of well-being neurotransmitters
- Improves fitness
- Improves mental health
- Reduces the risk of developing diseases
Explanation:
Performing physical activities helps to build a healthy relationship with yourself, in the sense that physical activity promotes health at all levels.
